Saint Bernard de Menthon, also called Bernard Of Aosta, or Bernard Of Montjoux, Italian San Bernardino De Mentone, (died 1081?, ; feast day May 28), vicar general of Aostadiocese (now in Italy) who reestablished and was patron of hospices at the summits of two Alpine passes, renamed after him the Great and Little St. Bernard passes. Also named for him in time were the hospices’ St. Bernard dogs, famed for rescuing lost travelers.

Bernard became concerned for the safety of travelers, often pilgrims to Rome, who crossed the mountains by way of the two passes leading into Aosta. The rest houses that he established there were tended by clerics and laymen and welcomed all travelers. In 1923 Pope Pius XI named him patron saint of mountain climbers.
